To all whom t may concern.'

Be it known that I, EDMUND KANDLER, a citizen of the United States, residing at Rochester, in;` the ycounty of Monroe and State of N ew York, have invented certain new and useful Improvements in 0phthal- 1nicTestLens Trays; and I do hereby declare the following tov be a full, clear, and exact description of thesame, reference being lhad to the accompanying drawings, forming a part `of this speciiicatiomand `to the reference-numerals marked thereon.

This invention relates to thatclass of trays used kfor holding the various lenses of an,

ophthalmic test `lens set, such as are employed by Opticians in testing the refractive properties of a patients eyes preparatory toy fitting eyeglasses. The obj ect of the invention is to provide an improved sanitary tray for ophthalmic testlenses of the kind described in my pending application Serial N o. 144,351, led January 25, 1917. To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure l is a plan view of a test lens tray constructed in accordance with my invention;

Fig. 2 is a transverse sectional view of the device shown in Fig. l, partly broken away;

Fig. 3 is an enlarged perspective view of` one of the inner channel partitions of the tray, one end -being broken away;

Fig. 4 is a longitudinal sectional view partly broken away and taken along the face of one of the plate partitions;

Fig. 5 is a face view of one of the plate partitions partly 'broken away;

Fig. 6 is a perspective view of one of the corner members of the frame, and n Fig. 7 is a similar view of the same in another position.

Similar reference numerals in the several figures indicate the same parts.

My improved test lens tray may be made of any form and of any size required to include the' requisite number of narrow lens chambers l, which may receive comparatively thin spherical and cylindrical lenses, and a comparatively few, say four, wider chambers 2 which may receive thicker prisprises two sheet neat appearance matic lenses. rIhe framey of theatray commetal channel end portions 3 and 3a, and front and rear ysheet metal channelframe portions k4f@ and 4. At the adjacentends of the frame and end portions, or the corners of the frame, the adjacent ends of themembers 3, 3a and 4:, 4u are yConnected by means of sheet metal corner members 5, shownin Figs. 6 and 7, struck upto iitover the ends. The frame, when assem bled in y thismanner, presents a pleasing,

with round corners and possessesV the qualities of lightness, rigidity and durability. i

In the constructiony illustrated, the lens chambers land 2 are entirely open at the' top andV only slightly obstructed at ythe bottom. Said chambers are formed by a series or plurality of substantially parallel inner metal Channel partitions 6 of whichV seven f are illustrated in the drawings, and two end frame portions 3 and 3a, also substantially parallel therewith. The spaces formed between the members 3, 3a, 6, 4 and 4a are` subdivided by a series or plurality of fiat sheet metal plates substantially parallel with the frame members 4 and 4f* into a series or plurality of chambers 1 and 2, idescribed above. The partitions 6 are spaced substantially equidistant from each other and from the end frame members 3 and 3a, forming a series or plurality of substantially parallel elongated chambers, each of which is subdivided by the ,plates 7 into a series or plurality of lens chambers or cells l, 2. The

sheet metal frame portions 3, 3a, 4l and 4a are struck up from sheet metal substantially U- shaped in cross section', with `the open sides directed inwardly. The ends of the plates 7 extend into theo en sides lof the members 3 yand 3a, and are inclined rearwardly from the vertical, so that they assume a substantially vertical position when the tray is tilted forwardly. Each of provided with a series or plurality of slots 8 extending downwardly from the top edge at substantially right anglesy to the length of the plate and to a `depth corresponding substantially to the depth of the partition 6. The slots 8 are spaced lfrom each other and, from the ends of the plate to coincide with the left hand walls 9 of the partition members 6. The right hand walls l1 of the partition members are also slotted, as'seen at 10, to a depth of substantially the full Width the plates 7 is f ot the Wall. The slots l0 are spaced and inclined from the vertical to Correspond with the Ispacing `and inclination of the plates 7. lVhen assembled, the partitions G tit over the plates 7, which extend into ythe slots l0, and the Walls 9 extend into the slots 8.

A VWire or lightrod 13 extends through each row ot Cells or chambers near its loottoni and is supported in the plates 7 by eX- tending through openings lproyided therefor in the plates. rEhe ends of the rods 13 are secured in position by being upset or bent exteriorly the front and rear plates. The rods or wires 13 serve as light and oonvenient supports vfor the test lenses in the cells.

Practically all portions of this iniproyed Ytest lens tray may he inade ot metal, c-ellu" other tough, readily eleansihle inaloid, or

2. ein ophthalmic test lens tray compris` ing a traine, a plurality ot inclined platev partitions extending across saidirame, an inverted substantially U-shaped channel partition supported on said plate partitions, and interlocking means between said partitions eoniprising a plurality otinelined slots extending substantially the` full depth ot' one Wall ot the channel partition adapted to engage the plate partition, stantially perpendicular to thel axis of leach ot the plate partitionsin engagement With the other Wall of the ehannel partition, and nieans secured in the plate partitions for supporting lenses.
